AUTOMOBTLLE JACK.

Application led February 17, 1922. Serial No. 537,242.

T 0 all whom t may concern:

, Be it known that l, JOSEPH H. HAM, a subject of the King of GreatBritain, and resident of the city of Brantford, county of Brant,Province of Ontario, in the Dominion of Canada, have invented certainnew and useful .improvements in an Automobile l ack, described in thefollowing specification and illustrated in the accompanying drawings,that form part o-f the saine.

The principal objects of the invention are, to facilitate the placingand operating of a jack under a car, thereby avoiding loss of time andinconvenience and other detrimental features of placing and .operatingthe jack of the ordinary kind which requires the operator to reach underthe car.

The principal feature of the invention consists in the novelconstruction and arrangement of parts, whereby the jack and operatingcrank therefor are rigidly mounted on a portable base and whereby saidbase -is provided with a carrying handle placed in a balancedarrangement.

ln the drawings, Figure 1 is a perspective view of my improved jack.

Figure 2 is a side elevational sectional view.

My improved construction of jack consists of a base 1 formed of a lengthof board sufficient to reach well under a motor'car and upon this baseis secured at one end the jack 2. This jack consists of a standard 3which is securely bolted to the base and is and part provided with athreaded spindle i support-l ed on a ball journal 5. )t sleeve memberard 3 is threaded on the spindle a and is provided with a spurproiection T whichl extends through a slot 8 in the standard. This spurproject-ion is arranged low down so that the jack may be utilized undera very low portion of the car structure in the event of a breakdown;

The upper end of the sleeve 6 is provided with a saddle 9 one side ofwhich is formed with a hinge joint 10 and to this hinged joint isconnected a block 11 which rests in the saddle and forms an extensionwhich.k

may be thrown back as shown in Figure 1, if desired.

T he spindle is operated 1Q secured to the lower end thereof and meshingwith this gear is aI pinion 13 which is jomnalled in an upward incline.

by a bevelled gear G slidable in the stand-l fin operating rod 14 isconnected to the stem of the pinion and this rod extends in an upwarddirection longitudinally of the base 1 and is supported at the outer endby standard 15 carrying a pivotal Sleeve bearing" 16 which eliminatesthe necessity for aligning the bearings.

A suitable crank wheel 17 is secured to the outer endvof the rod 14.This is arranged at ak height which enables it t0 be very easilyoperated and the length of the board is such that when the jack is undern wheel will be clear the part to be raised the portion of the of any ofthe overhanging car.

It will be readily seen that by reason of the mounting of the jack on abase and supporting the opera-ting rod a distance from the jack enablesthe jack to be placed in position under the load without the necessityof the operator stooping and reaching under the car. ln order to furtherfacilitate the handling of this jack l provide a standard 18 arrangedintermediate of the length of the base and so placed as to balance thejack. This standard is provided with a handle 19 at the top and also hasa sleeve portion 20 through vwhich the rod 111 extends andis supportedthereby.

The advantages of the use of a jack such as described will be readilyapparent and supported'from the top of the standard at the other end ofthe base, and a crank member Vconnected to the upper end of the rod.

A jack, comprising, an elongated base, a lifting member secured at oneendy thereof, a standard secured at the other end of said base andhaving a pivotal sleeve bearing, a rod journalled in said sleeve bearingand extending to and connected with the lifting member, and a crankconnected with the free end ofthe rod.

4l, A. jack, comprising a base formed of a plank, a lifting membersecured to one end of the plank7 :L standard secured to the other end ofsaid plznnlf,v an operating rod extending from the lifting member to thetop of said standard and j ournalled therein, a Crank on saidoperatingrod, and astandaid provided with a handle secured to the base and inbalance bet-Ween the ends.

5. A jack, comprising a base, en operating handle supported from liebase, a; lift; ing member connect-eu with the operating handle having :Lsloted Standard, and a spur on the nioveablerend of the liftinginernberextending through the slot in the stendard.
